The Central Bureau of Investigations (CBI), on Thursday, filed a supplementary chargesheet in the 1993 serial blast case against one of the under-trials, Feroz Rashid Khan, in order to disprove his claim of mistaken identity.

Khan had claimed in the past that his name was 'Hamza' and not Firoz Khan alias Firoz Taklya, who, according to the agency, was the one involved in the serial bomb blast. The agency, in its 90-page document, has relied on as many as 12 witnesses, who have confirmed the identity of Feroz Khan.

Special public prosecutor Deepak Salvi told dna: "There was a passport case pending against Khan in Thane. We succeeded in gathering evidence from that case. We have confirmed his identity with evidence from the ration and passport offices."

The CBI contention was, however, contested by the advocate appearing for Khan on the ground that the agency had not informed the defence about the evidence, and demanded time in order to argue over it.
The court adjourned the matter to June 23, when it will decide whether to take cognizance of the documents or not.

According to CBI, the 54-year-old accused is a close associate of Dawood Ibrahim, and helped land RDX and firearms in Mumbai prior to the 1993 serial blasts. Between 2004 and 2010 (before his arrest in February 2010), Khan divided his time between West Asia and Koparkhairane, a village in Navi Mumbai, and lived under an assumed name. He allegedly made a living forging passports and running a mobile phone business.

The agency now claims the documents it has are under his real name and had submitted them in the court.
